The picture on the leaflet

Children - in the third world presumably.

Key wording

'HELP HELP HELP . . .
THE THIRD WORLD . . .
The clothing that is collected from you kind and caring people . . . is made available for the people in the most poorest [sic] and underdeveloped countries. . . . let them have some of the things we take for granted. . . . These people struggle against poverty and hunger . . .
you are helping an adult or child to survive.'

Will the clothes be given to these people or will they be sold?

'The clothing . . . is made available for the people' [line 12]

The leaflet's vague on this, but it more-or-less implies the clothes will be given to the needy.
